HYDROKINETIC MECHANISM.`

Application led April 5,

To all fw hom t may concern Be it known that I, JOHN C. DAYNIX, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a certain new and useful Improvement in Hydrokinetic Mechanism, whereof the following is a specification, reference being had to the accompanying drawing.

My invention relates to engines of the hydraulic ram class. It is the usual practice to continuously supply water to such a ram with the effect that the ram is intermittently operated to raise avery small portion'l of the water thus supplied but'all of the water supplied to it during each interval in which the moving parts of the ram are returning to their initial positions for another impulse is wasted. It is thel object of lmy invention to intermittently supply such an impulse engine or group of engines with water; the intermissions of the supply being so timed as to correspond with the intervals of operation of such engine; so as to minimize the amount of water wasted; the eifect of my invention being to supply water to such an engine only when it -is ready to receive it and to withhold the water supply during such intervals as are required for the parts of the mechanism to resume their initial position to receive the nent charge of water, and to render the gravitative acceleration of the separate charges of water effective in the operation of said engine.

As hereinafter described, my invention includes automatically intermittently operative water charging mechanism capable of receiving, measuring and intermittently dispensing charges of waterv of predetermined volume and at predetermined intervals, from the body of water to be supplied to the apparatus to which it is to be supplied.- In the form of my invention hereinafter described,

suchV charging mechanism includes a tiltable measuring and dispensing trap normally presented in position to receive water from said supply but arranged to automatically tilt from that position when it has received a predetermined quantity of water and, by its tilting movement, shut ofil communication with the supply, and dispense, to the ram Specification of Letters Patent.

mechanism, the charge of Water which has been received by said trap; said trap having means t0 adjustably vary its operation both as to the volume of water received for each charge and as to the intervals of time between its tilting movements; so that such charging mechanism may be calibrated in accordance with the requirement of the ram mechanism it supplies.

My invention includes the various novel features off construction and arrangement hereinafter more definitely specified.

"In said drawing; Figure I i's a vertical sectional view of an apparatus embodying my invention; p-arts thereofbeing shown'in elevation. v

Fig.`II is a fragmentary planv sectional view of said apparatus, taken on the line II II in Fig. I.

iig. III is a vertical sectional view of one of the check valves through which water is received by the rams shown in Figs. I and II.

Fig. IV is a vertical sectional view ofthe water inlet valve of the tiltable trap shown in Figs. I and II; in the open position shown in Fig. I.

Fig. V is a sectional view of the valve shown in Fig. IV, but with the valve turned to closedfposition, corresponding with the position of said trap shown in dotted lines in Fig. I.

I iind it convenient to mount my improved mechanism in a tank l, indicated in Figs. I and II, which may be conveniently formed of reinforced concrete, extending below the level of the'body of water 2 from which the apparatus is to be supplied. l/Vater is admitted from vsaid supply 2 through the perforated screens 3 to the inlet conduits 4C which are controlled by the valves 5 and connected with the valve tube 6. Said valve tube 6 is held stationary and provided with a circumferential series of three ports 7 adapted to register with the ports 8 in the valve casing 9, as indicated in Figs. I, IV, and V. Said valve casing is a fixture in the tiltable ytrap 11 which is thus pivotally supported upon said lstationary valve tube 6 and contains the chamber 12 in which the charge of water 14 isreceived.

Said trap 11 is so proportioned that when empty it gravitates to the position shown in ull lines in Fig. I, but, when fully charged with water, gravitates to the position shown in dotted lines in said i'igure and is conveniently provided with the counterbalance i6 which may be adjusted by turning it on the screw shaft 17 which is mounted upon the bottom oi said trap ll, in rigid relation therewith, so that the quantity or water le necessary to overbalance said trap to the position shown in dotted lines in Fig. l may be variably predetermined by the adjustment of said counte balance 1G. Said trap il has the discharge outlet i8 which is normally closed by the lap valve 19, in the position shown in F ig. Said valve 19 is pivoted at 20 upon the valve lever 21 which is 'ulcrumed at 22 upon said trap l1 and depends in ope 'ative rela-tion with the roller 23 which is pressed into enga-gement therewith by the spring 24 in the stationary housing 25, by pressure ot' said spring upon the collar 26 on the plunger 27 which carries said roller and is mounted to reciprocate in said housing 25. Said housing` 25 is conveniently fixed upon the hopper which may be supported beneath the discharge end of said tiltable trap ll in any suitable manner, conveniently by the I-beams 3l and 32 which extend transversely in said tanlr l as indicated in Figs. I and H. Said hopper 80 is thus adapted to receive the water discharged from said trap ll through its outlet 18 aforesaid; such discharge being effected by the weight or" the charge water 14 thrusting the valve 19 open to the position indicated in dotted lines in F ig. l, when said trap is tilted downwardly to the position shown in dotted lines in said ligure; the ulcrum 22 of said valve lever 2l being then below the level oit said spring pressed roller 23 so as to free said valve 19 and its lever 2l from the pressure ot said spring 2st which normally keeps said valve shut. Said hopper 3() is directly connected with the conduit 3d, conveniently :Formed in sections, as indicated in Figs. l and l1, and leading to the ram mechanism so as to supply water thereto in successive charges le at intervals predetermined by the position of the valves That is to say the rate at which such charges are received in the tra p l1 and dispensed therefrom is dependent upon the rate of flow of the water :from the body 2 to said trap ll which latter rate is controlled by said valves The mechanism above described may be utilized to intermittently supply water to a hydrolinetic machine oic the ram type of any suitable construction or arrangement. However, l prefer to employ the speciiic construction and arrangement shown in Figs. l and II, wherein said conduit 34 is connected with the base 86 supporting a group of iive rams including two small rams, 38 and 39, which are of the saine size; two larger rains 40 and 4l which are olf the same size, but larger than said rams 38 and 39, and one ram 4t2 which is larger than any of the others. Aside from the fact that they are of diiierent sizes, said rams 38, 39, e0, eil and Ll2 are constructed and arranged and opera-te alike. Each of said rams includes a dome i3 in which air is conined under| pressure indicated by the gage le and regulated by the valve 4:5 which is adjustable to permit the automatic escape of air from said domes 4-3 through their respective pipes et, it and when the pressure of said air exceeds a predetermined degree. Said domes d3 are respectively mounted upon respective base plates 48 oi said base 36 and is provided with a group of four water inlet check valves which may be of any suitable form or construction, but are conveniently or the puppet type, best shown in Figlll, wherein the valve casing is provided with the seat il for the reciprocatory puppet valve which is adapted to be raised by water iowing upwardly from said base 36 to said domes d3 through said check valves, but which is normally closed, by gravity, in the position shown in Fig. III. When said valves 50 are thus closed, the water which has been injected through them into the domes Li3 against the compressedair therein, is of course prevented from returning through said valves, but is then driven out of said domes d3 by the compressed air therein, through the discharge ports 55 which are convenient-ly con centrically arranged with respect to the groups of said valves 50 in the respective engines. As shown in Fig. l, said ports are respectively provided with die-,charge conduits 56 leading to the manifold i? which is common to all of said discharge conduits and through which the water is conveyed to its destination in the direction of' the arrow shown on said manifold in Fig. l. l also nd it convenient to provide each of said conduits 56 with a check `valve 58, and said valves 58 may be oi the same construction and arrangement as the valves i0 and shown in Fig. HI.

The mechanism above described operates as follows: Said valves 5 l'ieing opened i the extent necessary to supply water to the group of engines at the rate it can be utilized by the latter; ,aid trap l1, which is normally in the position shown in :full lines in Fig. I, in which its inlet ports ''are open, is gradually filled, to the level indicated,

with a water charge lli and, thereupon, said trap is automatically tilted, by the weight of said water charge 14., from the position shown in full lines in Fig. l to the position shown in dotted ylilies in said figure, thus automatically closing the inlet ports 7 and opening the outlet port 18 of said trap l1 and discharging that Water charge coivn- Wardly through the conduit 34 into the engine base 36. Said conduit 34 is so proportioned both in diameter and length that the Water thus transmitted therethrough attains the desired velocity when it reaches the inlet valves 50 of the respective engines so as to open the latter and pass into the respective domes 43 in opposition to the pressure of the air which is compressed therein. During the interval of time While the puppets 52 of said valves 50 are resuming their initial closed position shown in Fig. III, and the Water is being driven from said domes 43 through said ports 55 and check valves 58 of the respective engines; said tank 1l automatically returns to its initial position, shown in full lines in Fig. I, because when thus emptied, it is overbalanced by the Weight 16 and therefore gravitates to the position shown in full lines in Fig. I, thus again opening its inlet ports 7; so that, by the time equilibrium is restored in said engine domes 43, another Water charge 14 is delivered thereto.

I find it convenient to provide said trap 11 with the air vent cock 60 and to also provide said base 36 with the air vent cock 61 to permit the operator to manually release any surplus of compressed air thereat.

The operation above described does not cause said engine to raise all of the Water of each charge 14 and the surplus is permitted to escape from said base 36 through the drain pipe 62, under control of the valve 63, to the drain tank from which it may be continuously or intermittently withdrawn.

Although I have shown a group of five hydrokinetic engines7 it is obvious that my invention may be embodied in mechanism including any desired number of units and, of course, may be embodied in mechanism including but a single ram. Moreover, it is obvious that said charging mechanism may be otherwise constructed and arranged.

Therefore, I do not desire to limit myself to the precise details of construction and arrangement herein set forth, as various Inodilications may be made therein without departing from the essential features of my invention, as defined in the appended claims.
